Samoset Middle School math students explored the unique capabilities of graphing straight lines as they participated in a holiday-themed activity introducing students to quadratics.
Eighth-grade honors students in Alicia Kroczynski’s math class learned how plotting straight lines can lead to creating curves. Utilizing KhanAcademy.org, students observed how quadratics were applied in the environmental modeling of grass in the Disney Pixar film “Brave.” After watching videos on how the graphic designers incorporated straight lines to create realistic curves, the students began to work on their own creations.
Using straight lines to connect a combination of dots, the students created various holiday objects such as a Christmas tree star, a snowman and a poinsettia. During the activity students also became familiar with popular quadratics vocabulary like axis, rays, angles and parabolic arches.
